i Claims.

This invention relates to book vending machines and has for its object to provide a book cabinet the accompanying drawings in which Figure l is a front elevation of the book vending cabinet.

Figure 2 is an end elevation thereof.

Figure 3 is a vertical cross section of the cabinet, with the section taken on the line 3a:3a: of Fig- 20 ure 1.

Figures 4 and 5 are vertical sectional views of the cabinet taken on the line im-4a: of Figure 1 showing the mechanism in its inoperative and operative positions.

Figure 6 is an enlarged detail sectional view of a portion of the cabinet and the operating mechanism, the section being taken on the'line 616a: of Figure 4;.

Figure 7 is a vertical sectional View of the re- 30 tarding cylinder and dashpot of the operating mechanism.

Figure 8 is a horizontal sectional view of the cylinder and dashpot, the section being taken on the line (ix-$3: of Figure 7.

In the several figures of the drawings like reference numerals indicate like parts.

The book vending cabinet forming the subject matter of this invention is adapted to provide means whereby a reference book, such as a city 40 directory, may be consulted and examined in public places, such as stores, depots and public buildings on the payment of a coin. The book is mounted in the cabinet so that it can be handled only by those who wish to use it for reference purposes.

As illustrated in the drawings the cabinet I is divided into the book compartment 2 and the mechanism compartment 3. The book'compartment is provided with the combined swinging door 50 and book support 4 to which the covers of the book 5 are attached so as to make the pages of the book readily available for examination when the door is released and swung open into the position illustrated in Figure 3. For this purpose is the combined cover and book support is mounted one-third to Ar- Camillus J. Kes- 1933,-SerialNo. 698,397 (01. 1944) on the square shaft 7, one end of which is journaled in a suitable bearing in the left hand end of the cabinet, while the other'end projects thru the partition 8 between the compartments 2 and 3 and is rotatably supported in the vertical base plate SA on which the operating mechanism is mounted. The inside of the combined door and book support is inclined so as to support the book at an angle.

The combined door and book support has a suitable counterweight Ill fastened thereto as illustrated in Figure 3 so as to slowly swing the support and the book back into the cabinetand close the door whenever the user has finished his examination of the book and takes his hands off from it.

The mechanism for locking the door and book support comprises the segmental plate I I which is mounted to the end of the square shaft and has the swinging latch 52 normally engagethe notch I3 thereof. This keeps the square shaft from rotating and holds the door locked in its closed vertical position.

To release the into the coin slot It so as to have it pass thru the coin chute I5 and drop into the temporary This receptacle has no "bottom but its inner wall is inclined so as to provide a large opening for the top of the receptacle and a small opening for the bottomthereof. In this way the opening in the top is made largeenough to receive the size coin which is to operate the releasing mechanism while the opening in the bottom is made small enough to prevent this coin from passing thru the receptacle but allow other smaller coins to do so. The receptacle is carried on the outer end of the sleeve 5? which is rotatablymounted on one end of the lever I8. This lever is fastened to the link at I9 and its opposite end is counterbalanced by the adjustable weights 2| and 22 which are'threaded thereon.

From opposite sides of the sleeve IT project the wings 23, 23 and these wings and the temporary receptacle I ii are so arranged with relation to the sleeve these combined parts will normally keep the receptacle "in a vertical position with the large opening at the top and the wings in a horizontal position while the counterweights ZI .and 22 balance the lever I8 with the sleeve I! in a horizontal position.

The temporary receptacle is thus normally held ready to receive any coin that is inserted into the coin slot and drops thru the coin chute. A coin inserted of the proper size is retained in the rethat the center of gravityof 4 ceptacle l6 and its weight overbalances the lever [B so that the link 2!! on which the lever is fulcrumed is swung to the right as illustrated in Figure 5. The latch I2 which is connected with the link 20 by means of the pin 9 is thus rocked to the right out of engagement with the notch l3 in the segmental plate I l.

The segmental plate and the shaft 1 on which it is mounted is then free to be rotated and permits the door 4 to be swung open by means of the handle 6 until the combined door and book support is brought into the position illustrated in Figure 3 in which a further movement of the door is arrested by the engagement of the inner end of the door with the shoulders 24, 24 provided by the plate members 25, 25 at each end of the book compartment.

While the combined door and book support l is being moved into the position illustrated in Figure 3, the segmental plate I! swings up and the pin 26 carried thereby engages one of the wings 23 and rocks it so as to turn the temporary coin receptacle into the vertical position illus trated in Figure in which the coin deposited therein is allowed to slide out therefrom. With the extra weight removed from the temporary coin receptacle, the lever E8 will then assume its original balanced position as soon as the segmental plate l! is moved back to its starting position on the closing of the door 4. When the lever l8 assumes its normal counterbalanced horizontal position, the latch l2 is moved by it to again engage the notch l3 in the segmental plate and hold this plate locked until the next coin is inserted for the release of the door and book support.

To prevent the combined door and book suptoo quickly while it is being opened and closed, a'retarding mechanism is provided. This mechanism comprises the cylinder 21 which is mounted to swing at 28 in a suitable bracket 29. As illustrated in Figure '7 a hollow piston 30 is mounted to reciprocate in the cylinder 21. In the bottom of this hollow piston is formed a small chamber 3!, the bottom of which is normally closed by the check valve 32. The valve stem 33 of this valve passes thru chamber 3| and a spring 33A which surrounds the valve stem within the hollow piston normally holds the valve seated to close the bottom of the chamber. In the valve 32 is provided a small opening 34 and in the closed top of the chamber 3| are provided a series of holes 35 so that the liquid used to retard the motion of the piston will have to leave the hollow piston thru the openings 35 and enter the piston thru the opening 34 in the valve 32.

The hollow piston is pivotally connected to the arm 31 which is pivoted on the vertical base plate 8A. A link 38 connects the arm 31 with the segmental locking plate H in order that the arm 31 is raised to pull the hollow piston outwardly on the opening of the door 4 and force it inwardly on the closing thereof. The restricted passage provided for the liquid in its flow from the hollow piston and back again thus operates to retard the movement of the combined door and book support.

To prevent the locking latch from being disengaged from the segmental locking plate H by keeping the counterbalanced lever l8 from swinging when the cabinet is tilted towards the rear, a pendulum latch 40 is pivotally mounted at 4|. The upper end of this latch is recessed to have it engage over the end of the counterbalanced lever l8 as it swings on the tilting of the cabinet. In this way the mechanism is locked while the cabinet is in an abnormal position.
